查询词典 nested

This should be performed by a two-level nested loop going though each index value for each segment.

由于要对每一段的每一个索引执行清空，所以这个操作应该是一个2级嵌套循环。

The most nested loop dominates the run time and is the only one mentioned when discussing O notation.

最嵌套闭环控制运行时间，并且是唯一一个提到在讨论符号。

Your code should never have multiple nested loops (a loop inside a loop inside a loop).

你的代码永远都不要有多个嵌套循环（循环之内的循环，循环内还有循环）。

To get the words from each line we use a nested while loop that uses an istringstream.

然后在内嵌的 while 循环中使用 istringstream 将每一行中的单词提取出来。

New bit allocation module reduces the two nested loop structure to one single loop.

新的位元分配模组将双回圈架构化减为单一回圈架构。

A program with a single loop and a nested loop (presumably loops that execute N times each) is O( N 2 ), even though there is also a O loop present.

程序的单回路和一个嵌套循环（大概循环每执行 N 次）为O （ N 2 ），即使有也是一个为O环本。

The remainder of the program consists of a nested for loop that tests each regular expression in list expressions against each string in list testStrings .

程序的其他部分由对在 list testStrings 里的每一个字符串测试 list expressions 中的每个正则表达式的一个嵌套的 for 循环组成。

Notice how this avoids the nested loop structure you wind up coding with os.walk and the callback functions you implement for os.path.walk, making it seem conceptually simpler.

请注意，这样做避免了用os.walk编码时的嵌套循环结构，也避免了为os.path.walk实现的回调函数，概念上更简单。

According to the spatial query technique and the topological predicates supported by ArcSDE,three methods are proposed for implementing topological join with ArcSDE,including Spatial Constraints Query Topological Join,Predicates Nested Loop Topological Join,and Filter-Refining 2 Phases Topological Join（FR2PTJ）.

根据ArcSDE提供的空间查询技术和拓扑关系谓词，提出了在ArcSDE平台下实现拓扑连接的三种方法，包括基于空间约束查询的拓扑连接方法、基于谓词的嵌套循环拓扑连接方法和过滤精化两阶段拓扑连接方法（FR2PTJ）。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。
